# How PinLink’s Service User Rebate Model Remains Sustainable PinLink’s Service User Rebate Model is based on the unique opportunities to unlock trapped capital that the RWA-tokenization model offers. Fees on Service User Rental Payments (which are the only fees available to regular DePINs) could not be used to provide rebates to end users as it would effectively just amount to recycling the same funds. By contrast, sales of fractional shares of the RWAs generate upfront capital payments that can be invested in generative yield-bearing activities that create new revenue sources for the PinLink ecosystem. These extra revenues can then be used to drive down costs for AI developers. As the Service User Rebate Fund grows over time, so do the yields, meaning ever greater discount opportunities for AI developers over time. Meanwhile, the Service User Rebate Fund is exclusively invested in proven, low-risk, high-reward strategies such as DAI Savings Rate Earning Strategies, Ondo US Dollar Yield and US Treasuries Strategies, or Pendle PT-YT Strategies. This minimizes downside risk whilst ensuring a steady stream of reliable income for rebates. --- # Agent Instructions: Querying This Documentation If you need additional information that is not directly available in this page, you can query the documentation dynamically by asking a question.
